Abstract

La présente invention concerne un procédé permettant de construire une structure de soutènement du sol à l'aide d'une plaque de fer. Le procédé comprend : une étape de pose de poutre en H qui consiste à poser vers la gauche et vers la droite plusieurs poutres en H espacées les unes des autres de l'avant à l'arrière, chaque poutre en H étant constituée d'une plaque intérieure, d'une plaque extérieure et d'une barre d'armature reliant la plaque intérieure et la plaque extérieure entre elles ; une étape d'excavation d'un premier lit ; une étape d'installation d'une première plaque de fer ; une étape de remplissage ; une étape d'excavation d'un second lit ; une étape d'installation d'une seconde plaque de fer ; et une étape d'achèvement de l'excavation du lit. Le procédé de la présente invention utilise une grande plaque de fer installée solidement sur la surface extérieure de la poutre en H et posée sur la partie intermédiaire de la profondeur de pose de la poutre en H, et une petite plaque de fer installée solidement sur la surface intérieure de la poutre en H de sorte que la partie supérieure de la petite plaque de fer est recouverte par la partie inférieure de la grande plaque de fer. Cela empêche non seulement le sol d'être versé dans les espaces intérieurs entre les poutres en H, mais élimine également la nécessité d'agrandir la profondeur de pose de la grande et de la petite plaque de fer, simplifiant ainsi la construction.
